Answer:
Domain: -∞<x<∞
range: -2≤y<∞
Step-by-step explanation:
domain is basically all the x values of the set. The parabola is facing up, meaning that it extends forever upward and out. This would mean the x values of the graph reach from neg to positive infinity
range is basically all the y values of the graph. The lowest y value, as shown by the vertex is -2. As said earlier, the parabola is facing upward, extending forever upward meaning that the highest y value is positive infinity
for infinity, always use these < or >
for numbers that are included in the graph such as -2 in this case, use ≤ or≥
